Alright, I have a question, I veered away from using strings for selection so now I use an integer. When the user enters a number then the game progresses. If they enter a wrong character it SHOULD give the else statement, however if I enter a letter or character the system goes into an endless loop effect then crashes. Is there a way to...

Sorry guys, I'm a noob. I know that some languages support type casting, but when I tried to do that here it failed, miserably. I've got an UITextField with number only pad, so I'm only getting numbers, and I need the output from that in my int, diff. Here's what I tried: NSString *outputNumber = [NSString stringWithFormat:@"%d", [textB...

How can I convert an int to a byte* at a certain index in a byte*? Ideally I would like to have something like: unsafe{ byte* igm=stackalloc byte[8]; igm[4]=4283; } It would set the first part of the bit to igm[4] and the rest into igm[5].
